It had not occurred to Emrys that they might get up and wander around, since that wasn't typical behavior at a dinner party, but he jumped at the chance (nearly literally; he was out of his chair in a moment). Anything to put some distance between himself at the dead or pretend-dead house elf, before he lost the contents of his stomach.

"Yes, let's," he said, throwing his napkin down on the empty dinner plate before him and turning to offer the young woman his hand. Of course, wandering about a stranger's house alone with a young woman wasn't exactly the sort of thing one commonly did. Well, Emrys did it fairly frequently, but usually he wasn't departing this blatantly. "Bring the box," he added, just to telegraph clearly to the rest of the party that their purpose in sneaking off together was related to the game and not to any mischief.

Well, his purpose was getting away from the house elf — but he didn't need to telegraph that either.
